💡 Installation Tips

  • Always add 10-15% waste for cuts and mistakes
  • Standard door opening: 3′ x 7′ (21 sq ft)
  • Average window: 3′ x 5′ (15 sq ft)
  • Use 1 lb of screws per 4 sheets (16″ OC studs)
  • Joint compound: ~1 gallon per 100 sq ft
  • Paper tape: 1 roll per 500 sq ft
  • Hang sheets horizontally when possible for fewer seams
  • Stagger seams for stronger walls
